A base64 string should be a multiple of 4 characters in length, not
contain any more than 2 padding characters and only contain padding
characters at the end of string. For example: Y3VybA==
Strings such as the following are considered invalid:
Y= - Invalid length
Y== - Invalid length
Y=== - More than two padding characters
Y=x= - Padding character contained within string
This is a regression since the switch to always-multi internally

Test 1316 was modified since we now clearly call the Curl_client_write()
function when doing the LIST transfer part and then the
handler->protocol says FTP and ftpc.transfertype is 'A' which implies
text converting even though that the response is initially a HTTP
CONNECT response in this case.
As the URI, which is contained within the DIGEST-MD5 response, is
constructed from the service and realm, the encoded message differs
from that generated under POP3.
...as it is no longer required following capability and authentication
changes and is now causing problems following commit 49341628b5 as
the test number is obtained from the client address in the EHLO.
...to the client address as this frees the RCPT strings to contain
just an email address and by passing the test number into curl as the
client address remains consistent with POP3 and IMAP tests as they are
specified in the URL.
As someone reported on the mailing list a while back, the hard-coded
arbitrary timeout of 7s in test 1112 is not sufficient in some build
environments. At Arista Networks we build and test curl as part of our
automated build system, and we've run into this timeout 170 times so
far. Our build servers are typically quite busy building and testing a
lot of code in parallel, so despite being beefy machines with 32 cores
and 128GB of RAM we still hit this 7s timeout regularly.

As curl will send a HELO command after an negative EHLO response, added
the same detection from commit b07709f741 to the HELO handler to
ensure the test server is identified correctly and an upload isn't
performed.
Rather than detecting the TO address as missing in the DATA handler,
moved the detection to the RCPT command handler where an error response
can be generated.
Moved the special SMTP server detection code from the DATA command
handler, which happens further down the operation chain after EHLO,
MAIL and RCPT commands, to the EHLO command as it is the first command
to be generated by a SMTP operation as well as containing the special
"verifiedserver" string from the URL.
This not only makes it easier and quicker to detect but also means that
cURL doesn't need to specify "verifiedserver" as --mail-from and
--mail-rcpt arguments.
More importantly, this also makes the upcoming verification changes to
the RCPT handler easier to implement.
